CVE-2026-34118 in Tapo C520WS

Resumen (Inglés)

A heap-based buffer overflow vulnerability was identified in TP-Link Tapo C520WS v2.6 in the HTTP POST body parsing logic due to missing validation of remaining buffer capacity after dynamic allocation, due to insufficient boundary validation when handling externally supplied HTTP input.  An attacker
on the same network segment could trigger heap memory corruption conditions by
sending crafted payloads that cause write operations beyond allocated buffer
boundaries.  Successful exploitation
causes a Denial-of-Service (DoS) condition, causing the device’s process to
crash or become unresponsive.
